Khoom Taw qhia
Calcium silicon alloyrau metallurgy yog alloy khoom tau los ntawm silica, txiv qaub thiab coke nyob rau hauv ib tug muaj zog txo cua ntawm 1500-1800 degrees. Silicon thiab calcium yog cov khoom tseem ceeb, thiab lawv kuj muaj ntau yam impurities xws li hlau, txhuas, carbon, sulfur thiab phosphorus. Feem ntauCaSi alloyqib xws liCa31 Si 60muaj tsawg dua 31% Ca thiab 50% -65% Si. Calcium muaj zog affinity nrog oxygen, sulfur, hydrogen, nitrogen thiab carbon nyob rau hauv molten hlau. Thaum calcium silicon ntxiv rau molten steel, nws yuav ua rau muaj zog exothermic nyhuv.

Daim ntawv thov scenarios
Steelmaking teb
Nws yog siv nyob rau hauv lub tom ntej refining theem ntawm converter steelmaking, lub sij hawm txo los yog refining lub sij hawm ntawm hluav taws xob rauv steelmaking, thiab cov txheej txheem refining sab nraum lub cub tawg. Nws tuaj yeem siv rau qhov tobdeoxidation, desulfurizationthiab muaj pes tsawg leeg zoo -tuning los tsim high- steel zoo, tshwj xeeb kev ua tau zoo steel, thiab lwm yam.
Casting teb
Hauv kev tsim cov hlau cam khwb cia, ntxiv rau deoxidation thiab purification, nws tseem ua lub luag haujlwm tu, uas pab tsim kom zoo -grained los yog spherical graphite, ua cov graphite hauv grey cam khwb cia hlau sib npaug, txo qhov nyiam ntawm cov hlau cam khwb cia dawb, thiab nce silicon, desulfurize, thiab txhim kho cov hlau cam khwb cia zoo.
FAQ
Q: Kuv lub tshuab steel tsis muaj hlau feeder. Kuv tuaj yeem siv cored hlau?
A: Tsis yog. Cored hlau yuav tsum tau xaim feeder rau hauv cov hlau molten. Peb xav kom koj yuav ib lub tshuab xaim ua ntej (kev nqis peev me me), lossis siv cov khoom siv thaiv kev pib, tab sis cov txiaj ntsig yuav qis dua.
Q: Dab tsi yog qhov txawv ntawm FeSi cored hlau thiab ntshiab calcium cored hlau?
A: FeSi cored hlau yog ua los ntawm CaSi hmoov, nrog cov ntsiab lus calcium tsawg (tsawg dua lossis sib npaug li 31%), tab sis silicon kuj muaj cov nyhuv deoxidizing. Ntshiab calcium cored hlau yog ua los ntawmcalcium hlau hmoov, nrog cov ntsiab lus calcium siab (Ntau dua lossis sib npaug li 97%), tab sis nws kim dua. Hauv tsev steel mills feem ntau siv FeSi cored hlau vim nws yog tus nqi ntau dua - zoo.
Q: Koj ua li cas kuaj cov ntsiab lus calcium hauv molten steel tom qab kho calcium?
A: Siv lub spectrometer lossis atomic absorption spectrometry. Feem ntau, cov ntsiab lus calcium uas nyob hauv cov hlau molten yuav tsum nyob nruab nrab ntawm 15-30 ppm. Hauv qab 10 ppm, cov txiaj ntsig kho calcium yuav tsis txaus; siab tshaj 40 ppm, nws yuav cuam tshuam qhov kev ua tau zoo ntawm cov hlau molten.
